An island territory off the coast of Australia has become the latest to be hit with a Zika travel advisory.

On Tuesday, the CDC added New Caledonia to its list of countries and territories with local transmission of the virus.

The virus, transmitted mainly via mosquitoes, has been identified in the US but only in people who’ve recently travelled to Zika hot spots. Once infected with Zika, only about 20% of people ever show symptoms, which most commonly include fever, rash, joint pain, and red eyes. There is no vaccine or treatment available for the virus. One reason Zika is troubling is because it has been linked with birth defects in babies whose mothers have had Zika symptoms and a neurological condition called Guillain-Barré Syndrome.

Here are the 37 countries and territories where the virus had been transmitted locally as of Wednesday, March 9:
